STDs are not transmitted by contact with saliva. And there is little or no risk from lap sitting, even without clothing. Without penetration of your penis into her vagina or rectum, you can put aside any fears of any STDs. You dont need testing and can safely continue sex with your girlfriend.
thanks for your care and answer.
i read there could be risk of hsv2 and hpv from rubbing even condom used. Is that risk just theory or proven experiences?
thanks again.
Look. Even without a condom, the average transmission risk for HSV2 from vaginal intercourse, if one partner is infected, is around once for every 1,000 exposures. Wtih a properly used condom, the risk is a lot lower still -- not zero, but still pretty safe.
